Five masses are placed in a plane as shown in figure. The coordinates of the centre of mass are nearest to

A

`1.2,1.4`

B

`1.3,1.1`

C

`1.1,1.3`

D

`1.0,1.0`

Text Solution

Verified by Experts

The correct Answer is:
C
`X_(C.M.)=(1xx0+2xx2+3xx0+4xx2+5xx1)/(1+2+3+4+5)`
`=(4+8+5)/(15)=(17)/(15)=1.1`
`Y_(C.M)=(1xx0+2xx0+3xx2+4xx2+5xx1)/(1+2+3+4+5)=(6+8+5)/(15)=1.3`
